| Abstract: | Aiming at the requirement on precious phase control of high-power friction welders,variable frequency control technology is adopted to realize phase control through variable frequency speed regulation and braking resistance. Control of phase angle is achieved by assigning values to change sensible parameters of the motor of the high-power friction welder. Furthermore,key sensible parameters are analyzed,calculated and verified through tests,so that the phase error of friction welded pieces is made less than 10. |
